I walk to my car in the morning, raining. I say "what the heck" the windows are all partly open. My wife starts blaming for not closing them the previous night, I'm losing my memory, you need to be more careful, etc... So I'm like no way but the evidence is solid against me. But then I get to thinking, it's been raining all night but the is only a little bit of water in the X5. I figure there is no way the windows have been open all night. It happened fairly recently. So, i'm thinking maybe it's a electronic glitch maybe from the rain...which I use as my defense. Then I think some more, I notice that all the windows are open but not at the same height. I remember this pattern..if you hold the open button on the remote it triggers the open all windows in a similar manner. Tada...I did something I never do that morning, I put the key in my pocket earlier in the morning sat down for breakfast and hence mystery solved....
